The officially recommended way of changing the username in a live-build is via grub entry, which concerns exactly the information that you've already been provided with.
lb config --bootappend-live "boot=live components username=live-user"

Just edit the file in lsb-release etc or create it and add these strings:
DISTRIB_ID=Debian
DISTRIB_RELEASE=11
DISTRIB_CODENAME=bullseye
DISTRIB_DESCRIPTION="Debian"then edit the file: etc/hostname
and put your distro the name you want and finally inside the folderetc/default c'è un file chiamato grub
open it and edit the string 8
GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`"
with
GRUB_DISTRIBUTOR="`lsb_release -d -s 2> /dev/null || echo Debian`"
put everything in includes.chroot by first creating a folder called etc and inside etc put the lsb-release and hostname files then create a folder inside etc called default and copy the grub file modifying it as I wrote above
